' This invention relates to a means for retaining the spindles of a textile machine against accidental removal from their supports.

An object of the present invention is to proijl. 'vide a simple and inexpensive retaining means for textile spindles enabling the spindles to be placed in position within their supports for rotation after removal for any reason by merely being forced past a spring pressed retaining member.

Another object of importance is that the retaining member is in the form of a resiliently mounted cap member on a stud formed on the spindle support and adjacent a flange on the spindle, the cap member being readily forced ,1; laterally to an oblique or tilted position by an operator when it is desired to remove the spindle.

And finally it is an object of the invention to provide a spindle retainer normally resiliently held in position to retain the spindle against removal from its support and which will allow and forming a part of this specification, I have shown my invention embodied in a textile spindle mounting of well-known type, but it will be understood that the invention can be otherwise embodied and that the drawing is not to be construed as defining or limiting the scope of the invention, the claims appended to this specification being relied upon for that purpose.

In the drawing:

Fig. 1 is a complete longitudinal view of a '40; spindle and its support showing the retainer forming the present invention in position thereon; and

Fig. 2 is a vertical sectional view of the retaining member showing its resilient supporting 745 means.

In the above mentioned drawing I have shown but one embodiment of the invention which is now deemed preferable, but it is to be understood that changes and modifications may be 'made within the scope of the appended claims without departing from the spirit of the invention.

Briefly, my invention may include the following principal parts: First, a spindle support; sec- 0nd, a spindle rotatably mounted therein; third,

a headed stud adjacent the spindle and mounted on said support; fourth, a conical cap member on said stud; and fifth, a spring surrounding said stud and normally resiliently retaining said cap member against the head of the stud and in po- 0 'sition to prevent removal of said spindle.

Referring more in particular to the figures of the drawing, I provide a. spindle support indicated generally at 10 and having the usual supporting bearing and guide for a spindle 11. Both 65 the support 10 and the spindle 11 may be of standard or conventional form, there being a driving portion 12 on the spindle 11 and a flange 13 at its lower end. As the support and spindle construction are or may be of well-known types, n further description is not thought to be necessary.

Adjacent the lowermost position of the spindle 11 and adjacent the flange 13 thereof is a pressed steel or other metallic retaining member 14 in the form of a conical cap member. This member .75 14 is supported upon a stud 15 having a head 16.

At the lower end of the stud 15 are provided screw threads 17 by means of which the stud 15 is secured fixedly into the support 10. Preferably an extension 18 forming an integral portion of the support is provided on a flanged portion of the support 10 for this purpose. A spring 19 surrounding the stud 15 resiliently forces the cap member 14 against the under side of the head. 16 but permits rotation of the cap member. With the cap member 14 in this position the spindle 11 cannot be removed from the support 10 for the reason the flange 13 is of suflicient diameter to be intercepted by the cap member 14. By manually moving the cap member to the tilted or laterally disposed position shown in dotted lines, however, the spindle 11 may readily be removed past the retainer 14.

To mount the spindle 11 upon the supportlO and within its bearings it is only necessary to press the spindle 11 downward with the flange 13 contacting with the cap member 14. By this movement of the spindle 11 the member 14 is pressed aside to permit theflange 13 to pass the retainer. With the spindle 11 in its lowermost or operative position the cap member 14 springs back to its normal or spindle retaining position in which position it is retained by its spring 19 until again manually operated to permit removal of the spindle 11.

What I claim is:

1. A spindle retainer for textile machines comprising in combination, a support, a spindle rotatably mounted therein, a flange on said spindle, a tiltable cap member mounted on said support 1 10 in a position to retain said spindle against removal from said support, and a spring retaining said cap member resiliently in position but permitting rotation thereof, whereby said cap member will be forced aside upon placing a spindle in position in said support and will prevent removal of said spindle from said support until manually displaced. I

2. A spindle retainer for textile machines comprising in combination, a support, a spindle rotatably mounted therein, a flange on said spindle, and a resiliently but rotatably mounted conical member on said support normally disposed adjacent said flange in position to retain said spindle and tilted to an oblique position when a spindle is being mounted on said support.

3. A spindle retainer for textile machines comprising in combination, a support, a spindle rotatably mounted therein, a flange on said spindle,

a headed stud on said support, a conical cap member thereon and resiliently held in position against the head of said stud, and movable laterally to permit mounting. said spindle in said support with its flange retained against removal by said cap member.

4. A spindle retainer for textile machines comprising in combination, a, support, a spindle rotatably mounted therein, a flange on said spindle, a headed stud on said support, a conical cap member thereon, a spiral spring surrounding said stud and resiliently holding said cap member against the head of said stud and in position to retain the spindle against removal from its support, and whereby said cap member is resiliently forced laterally when a spindle is being mounted in said support. ,r IRVING R.
